Application filed April 22, 1905. Serial No. 256,898.

.ence being had to the accompanying drawgMy invention Prelates to wheeled Scrapers, and has for its object to provide certain improvements in Scrapers of the type illustrated and described in Letters Patent of the United States No. 744,856, granted to me Novemberl 24, 1903.

My present improvements relate to the construction and operation of the drafthooks, to mechanism for raising the pan from loading partly to carrying position without progressive movement of the scraper, and to certain other features of construction which will be hereinafter described.

What I regard as new is set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved scraper, one wheel being removed and the pan being shown in loading position. Fig. 2 is a crosssection on line 2 2 of Fig. 1. Fig. 3 is a detail illustrating the position of the drafthoolrs and the pan in dumping. Fig. 4 is a side elevation, one wheel being removed, showing the pan in carrying position. Fig. 5 is a sectional detail illustrating the connection between the draft devices`and the panelevating mechanism. Fig. 6 is a front view of the parts illustrated in Fig. 5. Fig. 7 is a plan view of my improved scraper. Fig. 8 is a detail illustrating the latch by which the pan is held in carrying position, and Fig. 9 is a detail illustrating the front portion of the tongue.

'lhe principal object of my present mvention is to provide a construction by which the pan may be raised from loading position by the draft of the team, but without progressive movement of the scraper, and as a further development of my invention it is my object to provide a construction by which the usual snatch or extra team may be employed to do the work of raising the pan from its loading position. In the construction illustrated and described in my patent above referredto the pan is raised to carrying position by the draft of the team, and inasmuch as this is effected by brake connections, which act upon the wheels, it is essential that the scraper move forward to effect the lifting of the pan; but this, as above described, is not necessary in my present construction.

A further object is to provide an improved arrangement of the draft-hooks by which they operate by gravity to release the pan when it is tilted for dumping purposes, the hook or hooks being held positively in engagement with suitable coacting devices, such as hooks or eyes, while the pan is in loading or carrying position.

The foregoing is a general statement of the more important features of my present invention, and I will now describe particularly the embodiment thereof illustrated in the accompanying drawings.

Referring to the drawings, 8 indicates the scraper-pan, which is provided at opposite sides with uprights or standards 9, by which it is suspended from the upwardly-turned rear-end portions 10 of draft-bars 11, the latter being connected with the tongue 12 in the usual way.

13 indicates the usual handles, which are secured to the sides of the pan and project rearwardly therefrom, as best shown in Figs. 1 and 7. i

14 indicates a bail the side portions of which extend along the sides of the pan 8, near the upper edge thereof, and are pivotally secured thereto `by pivots 15, as shown in Fig. 1. The forward ends 16 of the bail 14 project over stops 17, secured to the sides of the pan near the front end thereof, and extend upward from said stops, as shown in Figs. 1 and 4. The rear portion of the bail 14 extends across the rear end of the pan and is. provided with a handle 18, as shown in 19 indicates draft-hooks which are pivoted at 20 to the draft-bars 11 and extend down beside the sides of the pan. The rear ends of said hooks are turned so as to engage corresponding hooks or eyes 21, secured to the sides of the pan. The upper ends 22 of the draft-hooks 19 extend rearwardly over the upwardly-projecting ends 16 of the bail 141 The arrangement is such that when the pan is in either loading or carrying position the IOO upper end portions 22 of the diaft-hooks rest upon the forward bail ends 16 of the bail 14, thereby holding the draft-hooks in engagement with the eyes 21. lVhen the pan is tilted in dumping, the upper ends of the draft-hooks are permitted to swing downwardly, thereby allowing the draft-hooks to disengage their respective eyes, as illustrated in Fig. It will be observed that by the construction described the draft-hooks act by gravity to release the pan, but are held in engagement therewith positively by means of the forward ends of the bail so long as the pan is in loading or carrying position.

I shall now describe the construction and arrangements by which the scraper-pan is raised from loading to or partly to carrying position.

23 indicates the usual carrying-wlieels, and 24 the arched axle upon the ends of which the wheels are carried. 25 indicates a frame in the form of a bail, the reaiwvardly-projecting ends of which are rigidly secured to the sides of the arched axle 24, as best shown in Figs. 1 and 4, said frame being perpendicular to the sides of the axle, as illustrated. The rear ends of the frame 25 are connected by pivots 26 to the upwardly-projecting ends 10 of the draft-bars 11, as is also shown in Figs. 1 and 4. 27 indicates braces running from the ends of the axle to the sides of the frame 25. 2S indicates a transverse shaft mounted in the forward portion of the frame 25 and carrying near its ends brake-shoes 29,. adapted to bear on the rims of the wheels 23. Said shaft is mounted so as to iock in its bearings and is provided with a lever 30, preferably near one end, which extends rearwardly at one side of the scraper, as shown in Figs. 1 and 4. By means of said lever the shaft 2S may be rocked, thereby applying the brakes to the scraper-wheels. The object of this construction is to provide for completing the elevation of the scraper-pan from loading to carrying position.

As best shown in Fig. l, when the scraperpan is in loading position the frame 25 is inclined downward and backward at an angle of forty-five degrees, more or less, and obviously by swinging the forward portion of said frame forward and downward the frame 25 operates as a lever fulcrumed upon the axlespindles to raise the rear portion of the draftbars together with the scraper-pan which is pivotally suspended therefrom on pivots 31, as shown in Fig. l. This may be accomplished by the draft of the team by moving the lever 30 to apply the brakes 29, but suoli operation requires that the wheels rotate, resulting in progressive movement of the pan. In order to avoid this necessity, I provide means actuated by the draft of the team independent of the progressive movement of from the ground. Such apparatus in the embodiment of my invention herein illustrated comprises a rod 32, mounted in suitable bearings 33 34, carried by the tongue, so as to be movable longitudinally thereof. Said rod extends to or beyond the forward portion of the tongue, as illustrated in Fig. 9, so that the usual snatch or extra team may be readily connected therewith.

35 indicates a collar mounted on the rod 32 in advance of the bearing 34 to limitV the rearward movement of said rod.

36 indicates a chain or other suitable ilexible connection, which is connected with the rear end of the rod 32 and extends around a pulley 37, mounted in a frame 38, carried by the tongue 12, as shown in Fig. l. T he rear end of said chain 36 extends up to and is connected with a suitable bracket or frame 39, secured to the front cross-bar of the' or its point of connection therewith adjusted f expeditiously.

By the construction described when the draft of the team is applied to the rod 32 it operates to pull down on the front cross-bar of the frame 25, thereby raising the pan i'n the manner already described, but without progressive movement of the scraper, since the frame 25 turns about the wheel-spindles as a fulcruin while the wheels do not rotate. lf desired, the pan may be raised in this manner completely to carrying position; but ordinarily it is so raised sufficiently high to clear the ground when the brakes are applied by operating the lever 30 and the scraper drawn forward, thereby completing the elevation.

Vhen the pan reaches its carrying position, it is held therein by means of a latch 43, pivotally connected by a pivot 44 with the front cross-bar of the frame 25, as shown in Fig. 3. Said latch is adapted to engage a plate 45 or other suitable stop carried by the scraper, preferably at the rear end of the tongue. The latch 43 is provided with an arm or lever 46, by which it may be readily operated to disengage the plate 45.

47 indicates the usual hook for holding the pan in a substantially vertical position when dumped.

4S indicates arms carried by and-proj ecting upwardly from the side members of the frame 25 adjacent to the wheels and carrying scrapers 49, which overlie the rims of the wheels and serve to remove mud therefrom.

lt will be obvious that my improvements may be applied to other forms of Scrapers than the specific kind illustrated andwde- ICO IIO

scribed, and inasmuch as, so far as I am aware, I am the first in the art to provide a construction by which the scraper-pan may be raised from loading to or partly to carrying position by the draft of the team without material progressive movement of the scraper I claim such invention broadly and do not restrict myself to the specific features of construction illustrated and described except in so far as they are particularly claimed. The terms employed in the claims are therefore to be construed generically. Furthermore, inasmuch as this .feature of my invention may be advantageously applied to other devices-such, for example, as log-cartsmy invention includes any and all such other applications thereof, and it is therefore to be understood that the term pan or scraperpan as employed in the claims is used in a generic sense to include not only a scraperpan, strictly speaking, but also any other device lifted bythe operation of the mechanism, whether it be a log or other weight occupying a similar relation to the lifting mechanism as the scraper-pan.
